Abstract: Mutant rice resistant/tolerant to ACCase inhibiting herbicides, in particular FOP herbicides, are listed in Table 1. The ACCase inhibiting herbicides used for selection include quizalofop. An exemplary mutant rice tolerant to an ACCase herbicide is disclosed, with a rice genome having G2096S or the equivalent, in the carboxyl transferase domain of the ACCase coding gene, using the Black-Grass numbering system. This mutation shows differential response to FOPs vs. DIMs herbicides, and a greater differential with comparable non-resistant rice lines. Methods to control weeds and methods to produce herbicide resistant rice including transgenic rice, are disclosed.

Abstract: A mutant rice resistant/tolerant to 4-hydroxyphenylpyruvate dioxygenase (HPPD) inhibiting herbicides is disclosed. The HPPD herbicides useful for selection and weed control include mesotrione, benzobicyclon, and combinations thereof. This rice is useful for weed control. Molecular markers useful for selection are also disclosed.
